test_bpf: assign type to native eBPF test cases
As JITs start to perform optimizations whether to clear A and X on eBPF programs in the prologue, we should actually assign a program type to the native eBPF test cases. It doesn't really matter which program type, as these instructions don't go through the verifier, but it needs to be a type != BPF_PROG_TYPE_UNSPEC. This reflects eBPF programs loaded via bpf(2) system call (!= type unspec) vs. classic BPF to eBPF migrations (== type unspec).
